Agenda

•  History of IT Industry – OSS – Hacker Culture – Community, Engineer’s career

11

IT industry

•  Vertical Integration – by ’80’s •  Horizontal – from ‘80’s •  Open Systems •  Internet, ‘90’s •  Open Source Software – from

1998 •  Web 2.0, 2005

12

Internet Age

•  Collaboration with somebody – OSS (Open Source Software) – Wikipedia – Facebook, twitter – Community – Youtube – 2ch – …

13

•  Blog •  SNS •  Cost of finding people becomes

all most zero.

14

Free software

•  GNU project, 1985 •  Linux, 1991 •  Ruby, 1993 •  Open Source Software, 1998

15

GNU Project

•  Distributed by Magnetic Tapes – you send money to FSF – FSF send you a tape (lately

CDROM) •  Not bazaar model

16

Internet

•  Xmosaic – 1993 •  Windows 95 – 1995 •  Open Source Netscape – 1998

17

OSS – Open Source Software

•  OSS and Free Software •  1998, Opened Netscape’s

browser source code •  Open Source Software

– Free Software: Freedom is important

– OSS: Not only freedom

18

OSS

•  Value – Freedom of Software – Global software development model

•  Evolution of software by collaboration

•  Cathedral and Bazaar – Eric Raymond, 1997

19

Bazaar

•  Software Development Model •  Engagement

– Users become Developers •  Develop by Community

–  individual vs. organization – volunteers

20

Hacker Culture

•  Common Value

21

Hacker Ethics

•  Sharing •  Openness •  Decentraization •  Free access to computers •  World improvement •  Levy, Steven. (1984, 2001). Hackers: Heroes of

the Computer Revolution (updated edition). Penguin. http://www.gutenberg.org/ebooks/729

22

Hacker Ethics

•  Access to computers—and anything which might teach you something about the way the world works—should be unlimited and total. Always yield to the Hands-On Imperative!

•  All information should be free •  Mistrust authority – promote decentralization •  Hackers should be judged by their hacking, not

criteria such as degrees, age, race, sex, or position •  You can create art and beauty on a computer •  Computers can change your life for the better

23

Hacker Culture, Common Value

•  Computers can change your life for the better •  rough consensus and working code

•  http://www.ietf.org/tao.html •  It’s better to ask forgiveness than permission.

•  If it's a good idea, go ahead and do it. It is much easier to apologize than it is to get permission. By Grace Hopper

24

Internet, Joichi Ito •  The ethos of the Internet

•  everyone should have the freedom to connect, to innovate, to program, without asking permission.

•  No one can know the whole of the network, and by design it cannot be centrally controlled.

•  This network was intended to be decentralized, its assets widely distributed. Today most innovation springs from small groups at its “edges.”

•  http://www.nytimes.com/2011/12/06/science/joichi-ito-innovating-by-the-seat-of-our-pants.html?_r=2&

25

What Happened to Yahoo, Paul Graham •  In 1998. Yahoo had two problems Google

didn't: easy money, and ambivalence about being a technology company.

•  Which companies need to have a hacker-centric culture? •  Any company that needs to have good

software.

•  http://www.paulgraham.com/yahoo.html

26

What Happened to Yahoo, Paul Graham •  Good programmers want to work at hacker-

centric culture. •  Without good programmers you won’t get good

software. •  http://www.paulgraham.com/yahoo.html

27

The Hacker Way (Facebook) IPO 2012

•  Code wins arguments •  Continuous Improvement and Iteration •  Open and Meritocratic •  Hackathon •  Bootcamp •  http://www.wired.com/business/2012/02/zuck-

29

Hacker-centric Culture •  Software Development in Internet Age

•  Hire good programmers •  Good programmers want to work with

good programmers at hacker centric culture

•  Build good work place •  Good programmers make good services

30

Web 2.0 •  Software products vs Internet Services

•  http://oreilly.com/web2/archive/what-is-web-20.html 9/30/2005

http://en.wikipedia.org/wiki/File:Web_2.0_Map.svg

31

Netscape vs Google •  A native web application, never sold or

packaged, but delivered as a service •  None of the trappings of the old software

industry are present. •  No scheduled software releases, just continuous

improvement. •  No licensing or sale, just usage. •  No porting to different platforms, …, just a

massively scalable collection of commodity PCs running OSS operating systems plus homegrown applications and utilities that no one outside the company ever gets to see.

Challenge of a Global Knowledge-Creating Organization

Ø 共同化（Socialization） This process focuses tacit to tacit. Ø 表出化（Externalization） This process focuses tacit to explicit. knowledge. Ø 連結化（Combination） Knowledge transforms from explicit to explicit. Ø 内面化（Internalization） Tacit knowledge is created using explicit knowledge and shared across the organization.

Knowledge needs to move from “Tacit to Explicit” and “Explicit to Tacit” This is especially hard for Global Companies!

49

How do we foster it? •  Tacit (implicit) Knowledge

•  material: manager, mentor, colleagues •  methods: work, job, study sessions, lunch,

drinking, hackerthons, SNS, … •  Explicit Knowledge

•  strategy, guideline, rule, procedure, tools
